No.  How should FreeType do that?  You input a glyph index, and the
library returns a rasterized image of the glyph, nothing more.  All
information FreeType can give is in the `FT_Face` structure and its
related sub-structures and siblings.

Such 'tagging' must be done at a higher library level: essentially,
it's you who specifies the parameters for the variable font, so it's
you who has to track them, too.
